GRADING-PLOW.

SPECEFICATION forming part of Letters Patent No. 670,300, dated March19, 1901.

Application filed May 16, 1900. Serial No. 16,894. (No model.)

To a/ZZ whom it may concern:

'Be it known that I, SAMUEL SMITH, a citizen of the United States,residing at Redcloud, in the county of Webster and State of Nebraska,have invented new and useful Improvements in Grading-Hows, of which thefollowing is a specification.

My invention relates to grading-plows; and one object of the same is toprovide a plow for this purpose which shall be simple in constructionand efficient in use and which will convey the dirt which slides up themoldhoard to an endless conveyer, which carries the dirt up to aninclined chute and deposits it on a discharge-chute, which carries itout of the track of the plow.

Another object is to provide simple and reliable means for adjusting thedepth of furrow and to add a simple device for steering or directing theplow.

l attain these objects by means of the construction shown in theaccompanying drawings, in which- Figure 1 is a plan view of agrading-plow. Fig. 2 is a side elevation thereof with parts broken away.Fig. 3 is a detail ofone wheel and the slotted guide. Fig. 4 is a detailof the discharge-chute. Fig. 5 is a detail perspective ofa fraginentofthe rudder and beam. Fig. o is a detail of the plow.

Like numerals of reference designate like parts in the different viewsof the drawings.

My machine consists, essentially, of a plow mounted on a beam, aconveyerwhiehcarries the dirt from the plow and which is supported in a chutemounted on two Wheels, and a second conveyer, which is mountedtransversely the tirst and serves to carry the dirt out of the track ofthe plow. These different parts, together' with the details pertainingthereto, will be taken up in the order named and all points of noveltyfully described.

The numeral 1 designates my plow, which consists of a moldboard 2,rigidly mounted on a landside 3, which is bolted to a plowbeam 4.'lhemoldboard 2 hasadiagonal cutting edge 5, which terminates in a pointf5, andformed integral therewith is an upturned flange orslice-cutter 7.'lhelandside 3 forms a support for the uioldboard 2, which is iirmlybolted tnereto. An arm 8 is formed integral with this landside andserves as a means for securing it to the plow-beam 4. A landplate 9 issecured to the bottom and side of the moldboard 2 and serves as a guidefor the plow.

For guiding the plow in turning corners a rudder is provided, whichconsists of a lever 10, pivotally secured to the forward end of theplow-beam by a staple and fitted with a steering-wheel 12, journaledtherein and constructed to be brought in Contact with the ground. Thearm or lever 1()is bent at right angles at 1U and 10b, and the rear endextends back within reach of the driver. In turning a corner he wouldgrasp the end of the lever and force the wheel 12 down to the ground andmanipulate the lever from right to left and back to turn the corner,after which it would be raised and thrown up on top of the machine outof the way, as it is not necessary except in turning.

The elevator for carrying the sod from the plow comprises an endlessbelt 13, which is mounted on rollers 14 and 15, anda chute 16, whichcontains said belt. The roller 14 is supported by the plow and journaledin the landside 3 at one end and in the slice-cutter '7 at the other.The upper roller 15 is journaled in the sides 1'7 of the chute 16. Thebelt 13 is provided with a series of L-shaped buckets, `which engage andcarry the dirt up and automatically dump it. The chute 16 is mounted onan axle 18, which is journaled in boxes 18, secured thereto, and thelower end engages a oi'ess-bar19. This bar is attached to the plow-beamat one end and extends transversely the machine and is oppositelysecured to a brace ortie rod 20,which extends from the forward end ofthe plow-beam to the outer end of the axle and ties the whole framefirmly together. By this arrangement the chute 16 is free to follow theupward or downward movement of the cross bar 19. The upper end of thechute is heavier than the lower, so that all danger of dragging isavoided. Two wheels 21 are keyed on `the shaft or axle 18,-a'nd a pinion22 is keyed thereon centrally thereof. This pinion 22 meshes with asecond pinion 23, keyed on a shaft 24, journaled in the sides 17 ofthechute. The pinion also meshes with a rack 25, which is secured to theinner or under side of the endless belt 13. This combination of ioopinion and rack 25 furnishes means for driving the eonveyer.

To enable the angle of the plow to be adjusted, the rear end of theplow-beam 4 is Iitted with a guide 26, which fits around the shaft oraxle 18. A lever 27 is pivotall y joined to the beam at and is threadedonthe shaft 18. A rack 28 is mounted ou one of the sides 17 of the chuteand in combination with a catch 29 serves to hold the lever 27 in anyposition desired. In operating this lever 27 to tilt the plow up thehandle is depressed, and as there is no positive connection between thesides 17 of the chute and the plow 1 the plow,

will be tilted up on the cutting edges of the moldboard,which alwaysrests on the ground. The pinion 23 will not be thrown out of ensagementwith the rack 25, since the lower end of the chute 16 follows themovement of cross-bar 19 and carries this pinion with it.

A pair of handles 8O are attached to the upper end of the chute 16, andsuspended by hooks 31 therefrom is a discharge-chute 32 for carrying,the sod out of the track of the plow. This chute 32 bears an endlessconveyer 33, which is provided with a series of aprons 34, havingrollerbearings 85, keyed on shaft-s 36. These rollers 35 run on a track87, supported on cross-pieces 38. This chute 32 is operated bygravity-that is, the sod which is dumped into it from the chute 1o willby its weight actuate the conveyer, as this chute is always set at asteep angle.

The operation of the various parts of my machine has already been given.The operation asa whole can be stated in a few words. In starting theplow it is set at an angle to the ground by means of the lever 27 andthe team started. This action will compel the plow to scoop up the soil,and after it has a good hold it can be once more brought into ahorizontal position. The dirt from the glow will be forced up themoldboard onto the chute 16, from whence it will be transported to thecross-chute. It will then drop on the cross-chute, actuate it, and becarried out of the way.

Having thus fully described myinvention, what I claim as new, and wishto secure by Letters Patent, is-

1. In agrading-plow, the combination, substantially as described, of aplow mounted on a beam, a chute abutting said plow and pivotally mountedon a shaft bearing two wheels keyed thereon, an endless conveyer mountedon two rollers one being,r journaled in the upper end of said chute andthe other being journaled in said plow, means for limiting the movementof said chute, and means for connecting said conveyer to said shaft toenable it to be driven thereby.

2. In agrading-plow, the combination,snb stantially as described, of ashaft bearing traction-wheels keyed thereon, a plow mounted on arearwardly-extending beam, means for pivotally securing the rear end ofsaid beam to said shaft, a chute abutting said plow and pivotallymounted on saidshaft, a conveyer mounted in said chute, and means forconnecting said con veyer and said shaft to permit the same to be driventhereby.

3. In a grading-plow the combination, substantially as described, with aplow mounted on a beam, of means for steering said plow which comprisesa lever pivotally attached at one end to the forward end of saidplowbeam, and a wheel journaled -in said level' and constructed to bebroughtincontact with the ground and to be raised out of contacttherewith.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit nesses.

SAMUEL SMITH.
